That is correct. I would say, the square root of a number is another number that, when you multiply it by itself, gives you the number you started with. Remember that a positive number always has two square roots, one positive and one negative. The square roots of 49 are 7 and -7, since 7x7=49, and also -7x-7=49.

6.98 lies between the two square roots of 49.

It has two of them: +7 and -7 .

The square root of 36 and the square root of 49.

The square root of 49 is: ± 7

The square root of 36 is 6 and the square root of 49 is 7 These are used as 42 is between 36 and 49.

No, it does not; it could be a fraction (or, what amounts to the same thing, a repeating decimal), a negative number (in fact every strictly positive number has 2 square roots, one positive, one negative, such as the square roots of 25 are 5 and -5), an irrational number (like the square root of 2), or an imaginary number (like the square root of -49).

49 is a composite number because it has more than two factors and it is also a square number

25 and 49.

49

Yes 49 is a square number because 7x7=49YES

You know to find out which out which number has been timed by itself to make the number in the square root. For example: If the number inside the square root is 49, you need to find out which number has been timed by itself to make 49. As you may know, the number inside the square root is always a square number, so I would advise you to learn the list of square numbers. 7 x 7= 49, so the square root of 49 is 7. Remember that Evaluate simply means work out. So when to asked to evaluate a square number, cube number, square root, cube root etc., simply just work it out. Evaluating powers and roots is grade D in maths.

The square root of 49 is 7.7 times 7 is 49, so the square root of 49 is 7. 7

7 x 7=49 so that is the 17th square number

It's not. Take 49 and 16 for example. The square root of the sum is the square root of 65. The sum of the square roots is 11.

7 and -7.

To figure this out, I always start with square roots I know, and that are close to 47. So, first, I would figure out that the square root of a number such as 36 is 6. The square root of 49 is 7. Now, since there are no other whole numbers between 6 and 7, and the square root of 47 falls between the square root of 36 and 49, we can say that the square root of 47 is between the whole numbers 6 and 7.

There are two of them. They are +7 and -7 .

49 is the square number of 7.

49 equals 72, and the next square number is 82 = 64.

49 = 7 x 7 so it is a square number.

To square a number (mathematically expressed as X2) you multiply it by itself. 49 is the square of the number 7, and 7 can be said to be the 'square root' of 49.

The square root of 49 is 7, so it is rational.

-1

Yes, a square number means that it is the product of a number times the same number, so if you can divide a number buy the same number you get the square root. 6x6=36 and the square root of 36 is 6. 7x7 is 49 and the square root of 49 is 7. Make sense?
